Answer: x=15
Step-by-step explanation: Since 3x+5 is equal to 50, you can write 3x+5=50, and 3x=45, x=15.
Answer: d. He multiplied when he was supposed to divide

Answer:
<u>Volume</u><u>:</u> 1135.82 yd³
<u>Surface Area</u><u>:</u> 657.12 yd²
Step-by-step explanation:
V = whl
12.2 · 9.8 · 9.5
1135.82
A = 2(wl + hl + hw)
2 · (12.2 · 9.5 + 9.8 · 9.5 + 9.8 · 12.2)
657.12
Answer:
972π cm³
Step-by-step explanation:
Okay so this container is a sphere, so you're going to want to use the volume of a sphere equation V = (4/3) * π * r³. In this case, you've got the diameter (d = 18), so divide by 2 to get r = 9.
So now you have all the variables you need to solve. Substituting those values into the volume equation, you get:
V = (4/3) * π * 9³ = 972π cm³.
